and -L35E
Explicit messaging is NOT available for CompactLogix -L20 and
-L30 processors, or 1769-ADN DeviceNet adapters.
•
User-defined fault actions to determine how the module and
connected drives respond to controllers in idle mode (Idle Action).
•
Bi-color (red/green) status indicators to report the status of the
module and channel communications.
•
Compatibility with various configuration tools to configure the
module and connected drive(s). The tools include an optional,
external PowerFlex 4-Class HIM (22-HIM-A3 or 22-HIM-C2S), and
drive-configuration software such as DriveExplorer v3.01 (or higher)
or DriveExecutive v4.01 (or higher).

tool, can be used with each drive. An AK-U0-RJ45-SC1 DSI Splitter
cable can be used to split the RJ45 connector on the drive into two RJ45
connectors.

Getting Started
Multi-Drive mode enables increased connectivity, where one to five
PowerFlex 4-Class drives can be connected per channel. All of the drives
are daisy-chained to the 1769-SM2 module over RS-485 as shown in
Figure 1.3.
Figure 1.3 Multi-Drive Mode Wiring Example
Up to 5 PowerFlex 4-Class drives
Wiring Tip:
The 1769-SM2 has an
integral terminating
resistor for each channel.
Thus, it is only necessary
to connect a terminating
resistor to the RJ45
terminal block at the last
drive on each channel.

In Multi-Drive mode, any channel can be configured for “RTU Master”
operation (Figure 1.4). This enables connection of up to 31 RTU Slave
devices, such as PowerFlex 7-Class drives with 20-COMM-H RS485
HVAC adapters.

Getting Started
Benefits of Multi-Drive mode include:
•
Lower hardware costs. Only one 1769-SM2 is needed for up to five
PowerFlex 4-Class drives per channel (15 total).
•
Controller can independently control, monitor, and read/write
parameters for all five drives on each channel (same functionality as
Single mode).
The trade-offs of Multi-Drive mode include:
•
Since the RS-485 ports are used for daisy-chaining the drives,
additional DSI peripheral devices cannot be used with the drives.
This includes an optional, external PowerFlex 4-Class HIM
(22-HIM-A3 or 22-HIM-C2S) or a 22-SCM-232 Serial Converter
module with a software tool. The AK-U0-RJ45-SC1 DSI Splitter
cable cannot be used to add a second connection for a DSI peripheral
device.

Preparing for an Installation
Consider the following when installing the 1769-SM2 module:
•
Verify that you have all required equipment. Refer to Required
Equipment on page 1-6.
•
A MicroLogix 1500 Base Unit or Compact I/O power supply has
limits in the amount of +5V dc and +24V dc current it can supply to
modules in its I/O bank. These limits depend on the catalog number
(e.g. 1769-PA2) of the power supply. A bank of modules must not
exceed the current limits of the MicroLogix 1500 Base Unit or I/O
bank power supply.
Refer to the MicroLogix 1500 User Manual (publication
1764-UM001) or the Compact 1769 Expansion I/O Power Supplies
Installation Instructions (publication 1769-5.14).
•
The module has a distance rating of four. Therefore, the module must
be within four modules of the I/O bank’s power supply.
2-2
Installing the Module
!
ATTENTION: Risk of equipment damage exists. The 1769-SM2
module contains ESD (Electrostatic Discharge) sensitive parts that can
be damaged if you do not follow ESD control procedures. Static control
precautions are required when handling the module. If you are
unfamiliar with static control procedures, refer to Guarding Against
Electrostatic Damage (publication 8000-4.5.2).
Removing Power
!
ATTENTION: Risk of equipment damage exists. Remove power
before installing or removing the 1769-SM2 module. When you install
or remove the module with power applied, an electrical arc may occur.
An electrical arc can cause personal injury or equipment damage by:
•
Sending an erroneous signal to your system’s field devices, causing
unintended machine motion.
•
Causing an explosion in a hazardous environment.
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical
resistance.

1X (Single mode)
back position
Description
Default setting — sets the 1769-SM2 module for Single mode
using a single drive connection (one drive per channel).
Important: In Single mode, only one drive can be connected per
channel. Connections to multiple drives must be removed since
all powered and connected hosts will respond to any message
sent by the module.
5X (Multi-Drive mode) Sets the 1769-SM2 module for Multi-Drive mode using up to five
front position
PowerFlex 4-Class drives per channel.
In Multi-Drive mode, DSI peripherals such as the 22-HIM-A3 /
-C2S Human Interface Module, 22-SCM-232 serial converter, etc.
CANNOT be used. They will not operate with the 1769-SM2
module or drives.
The specific number of drives used in Multi-Drive mode for each
channel and a unique address for each drive must be configured
using 1769-SM2 module parameters. For instructions, see
Setting the I/O Configuration (Multi-Drive Mode Only) on
page 3-14 and Setting Drive Node Addresses (Multi-Drive Mode
Only) on page 3-16.
NOTE: In Multi-Drive mode, each channel can be independently
configured for Modbus RTU Master operation by setting the
respective channel’s [DSI I/O Cfg] parameter to “5” (RTU Master).
This enables up to 31 RTU slave devices, such as PowerFlex
7-Class drives with 20-COMM-H RS485 HVAC adapters to be
connected to that channel.
Important: A new switch setting is recognized only when power is
applied to the module, or the module is reset. If you change
a setting, cycle power or reset the module.
The Configuration Mode Switch (SW1) and Operating Mode Switch
(SW2) settings can be verified by respectively viewing module
Parameters 01 - [Config Mode] and 02 - [DSI Mode] using an
optional, external PowerFlex 4-Class HIM, DriveExplorer software or
DriveExecutive software.

Panel Mounting Procedure Using Module as a Template
The following procedure enables you to use the assembled modules as a
template for drilling holes in the panel. Due to module mounting hole
tolerance, it is important to follow these steps:
1. On a clean work surface, assemble no more than three modules.
2. Using the assembled modules as a template, carefully mark the
center of all module-mounting holes on the panel.
3. Return the assembled modules to the clean work surface, including
any previously mounted modules.
4. Drill and tap the mounting holes for the recommended M4 or #8
screw (not included).
5. Place the modules back on the panel, and check for proper hole
alignment.
6. Attach the modules to the panel using the mounting screws.
DIN Rail Mounting
The 1769-SM2 module can be mounted using these DIN rails:
• 35 x 7.5 mm (EN 50 022 - 35 x 7.5)
• 35 x 15 mm (EN 50 022 - 35 x 15)
When mounting the module to a DIN rail, make sure that the latches are
closed and properly securing the module.
Installing the Module
2-9
Replacing the Module within a System
The 1769-SM2 module can be replaced while the system is mounted to a
panel (or DIN rail).
!
ATTENTION: Risk of equipment damage exists. Remove power
before installing or removing the 1769-SM2 module. When you install
or remove the module with power applied, an electrical arc may occur.
An electrical arc can cause personal injury or equipment damage by:
•
Sending an erroneous signal to your system’s field devices, causing
unintended machine motion.
• Causing an explosion in a hazardous environment.
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical
resistance.
1. Remove power.
2. Unplug the communications cable from each port (CH1, CH2, CH3)
on the 1769-SM2 module. Note each drive and the port to which it is
connected.
3. Remove the upper and lower mounting screws from the module (or
open the DIN latches using a flat-blade screwdriver).
4. On the right-side adjacent module, move its bus lever to the right
(unlock) to disconnect it from the module being removed.
5. Gently slide the disconnected 1769-SM2 module forward.
If you feel excessive resistance, make sure that you disconnected the
module from the bus and that you removed both mounting screws (or
opened the DIN latches).
TIP: It may be necessary to rock the module slightly from front to
back to remove it or, in a panel-mounted system, to loosen the screws
of adjacent modules.
6. Before installing the replacement 1769-SM2 module, be sure that the
bus lever on the right-side adjacent module is in the unlocked (fully
right) position.
7. Slide the replacement 1769-SM2 module into the open slot.
2-10
Installing the Module
8. Connect the 1769-SM2 module and adjacent modules together by
locking (fully left) the bus levers on the 1769-SM2 module and the
right-side adjacent module.
9. Replace the mounting screws (or snap the module onto the DIN rail).
10. Plug the appropriate communications cable into its respective port on
the 1769-SM2 module.
11. Restore 1769-SM2 module configuration using an appropriate
configuration tool.
Connecting Drive(s) to the Module
NOTE: For Single or Multi-Drive mode, there is a maximum cable
distance limit per channel. See DSI Cable Requirements on page A-2 for
more information.
For network wiring diagram examples, see the following figures:
1769-SM2 Operating Mode
Single mode (Default)
Multi-Drive mode
Multi-Drive mode with Modbus RTU Master
Network Wiring
Diagram Example…
Figure 1.2
Figure 1.3
Figure 1.4
Single Mode
When the 1769-SM2 module is operated in Single drive mode, each
drive is directly connected to a channel port (CH1, CH2 or CH3) on the
module. Use either a 22-RJ45CBL-C20 communications cable for each
channel or AK-U0-RJ45-TB2P terminal block connectors and twisted
pair network wiring (Belden No. 3105A or equivalent).
Important: When connecting a drive to the channel port using
AK-U0-RJ45-TB2P terminal block connectors and twisted
pair network wiring, the following drive parameters MUST
be configured to the settings shown so that the 1769-SM2
module will communicate with the drive:
Drive Parameter
A103 - [Comm Data Rate]
A107 - [Comm Format]
Setting
“4” (19.2K)
“0” (RTU 8-N-1)
Changes to these drive parameters require the drive to be
reset for the new settings to take effect.
Installing the Module
2-11
When connecting a drive to the channel port using 22-RJ45CBL-C20
communications cable, the above drive parameters do not require
configuration because the drive senses that a DSI peripheral is connected
and it ignores these parameter settings.
Multi-Drive Mode
For Multi-Drive mode, each channel port MUST be connected to the
drives via daisy-chaining using AK-U0-RJ45-TB2P terminal block
connectors (one for the port connection and one for each drive
connection) and twisted pair network wiring (Belden No. 3105A or
equivalent). The 22-RJ45CBL-C20 communications cable and splitter
cables cannot be used.
Important: The following drive parameters MUST be configured to the
settings shown so that the 1769-SM2 module will
communicate with the drives:
Drive Parameter
A103 - [Comm Data Rate]
A104 - [Comm Node Addr]
A107 - [Comm Format]
Setting
“4” (19.2K)
Value of Drive Addr x parameter in the
1769-SM2
“0” (RTU 8-N-1)
Changes to these drive parameters require the drive to be
reset for the new settings to take effect.
Installing the Module
Grounding the Module
The 1769-SM2 module is intended to be mounted to a well-grounded
mounting surface such as a metal panel. Additional grounding
connections from the module’s mounting tabs or DIN rail (if used) are
not required unless the mounting surface cannot be grounded. Refer to
Industrial Automation Wiring and Grounding Guidelines, publication
1770-4.1, for additional information.
Shielded Connector Grounding Requirements
When using the 22-RJ45CBL-20 cable, which has shielded connectors,
the shields are all grounded to the chassis terminal block on the
1769-SM2 module (item 11 in Figure 1.1). However, the user must:
•
Install a wire from the chassis terminal block on the 1769-SM2
module to a grounded, conductive surface (i.e. metal panel). See
Figure 2.6.
•
Remove the shield connection to chassis ground at the drive I/O
block shield terminal.

The 1769-SM2 module’s RJ45 connectors (CH1, CH2, and CH3), which
are electrically common, should be grounded by attaching a drain wire
from the 1769-SM2 terminal block (item 11 in Figure 1.1) to a grounded,
conductive surface (i.e. metal panel). If shielded cable (not required) is
used, the cable shield should also be connected to the chassis by
attaching the cable shield to the 1769-SM2 terminal block (Figure 2.7).
Good wiring practice dictates that the cable shield be terminated to the
chassis at only one point along the cable to prevent ground loops from
occurring. The chassis terminal block on the 1769-SM2 module is
provided as a convenient place for this termination.

Configuration Methods
The 1769-SM2 module has two methods of configuration, which are
determined by the Configuration Mode Switch (SW1 in Figure 2.1):
• Controller mode—The 1769-SM2 uses the configuration data
downloaded from the controller on power-up and when the controller
is placed in run mode. The data is configured using RSLogix 500,
RSLogix 5000 or RSNetWorx for DeviceNet.
• Parameter mode—The 1769-SM2 uses its internal parameter settings
to configure the module. The data is configured using an optional,
external PowerFlex 4-Class HIM, DriveExplorer, or DriveExecutive.
Only one method can be selected, and it is used for all three channels.
Controller Mode
When the Configuration Mode Switch (SW1 in Figure 2.1) is in the
default CONT (Controller) position, the 1769-SM2 uses the configuration
data downloaded from the controller on power-up and when the controller
is placed in run mode. Depending on the controller, configuration data is
allocated and entered using RSLogix500 or RSLogix 5000.
Configuration Data
The 1769-SM2 module contains a set of 42 words of configuration data
that is used to configure the module's behavior (Table 3.C). A software
tool, such as RSLogix 500, RSLogix 5000 or RSNetWorx for DeviceNet
is used to read/write the configuration data.

Configuring the Module
The configuration data directly correlates to the module parameters.
Refer to Appendix B for more information.
Entering MicroLogix 1500 Configuration Data Using RSLogix 500
Before v6.30
Earlier versions of RSLogix 500 can be used, but the configuration data
must be entered in raw form in a Data Config table following the format
in Table 3.C. However, RSLogix 500 v6.30 (or higher) is highly
recommended for use with the 1769-SM2 because it contains a dedicated
I/O configuration window for the module to simplify the configuration
process. Version 6.30 is also required to perform explicit messaging,
such as parameter reads/writes.
Entering MicroLogix 1500 Configuration Data Using RSLogix 500
v6.30 (or higher)
Allocate and enter the configuration data by performing these steps:
1. In the RSLogix 500 treeview, double-click on I/O Configuration to
open the I/O Configuration window. Double-click the 1769-SM2 in
the Current Cards Available list to add the module to the controller
system. Select the “1769-SM2” row and click the Adv Config
command button. The 1769-SM2 I/O Configuration window
(Figure 3.1) appears.
Figure 3.1 I/O Configuration Window and Expansion General Configuration Screen
Configuring the Module
3-5
2. Enter the Series letter of the 1769-SM2, which can be determined by
checking the data nameplate label on the module (item 9 in
Figure 1.1).
The I/O image of the module can be up to 31 words of Input and 31
words of Output, depending on the mode selected (Single or
Multi-Drive) and the number of drives connected. A Single mode
system with one drive on each channel requires 7 Input words and 7
Output words. A Multi-Drive mode system with five drives on each
channel requires 31 Input words and 31 Output words. See Table 3.A
or Table 3.B to determine the number of Input Words and Output
Words to enter for your system.
The Extra Data Length field can only be set to a size of 0 or 42. If the
controller will contain the configuration data for download to the
1769-SM2 module (Configuration Mode Switch SW1 set to CONT
position), set this value to 42. If the configuration data will be
contained in the 1769-SM2 parameters (Configuration Mode Switch
SW1 set to PARAM position), this value should be set to 0. See
Table 3.C for descriptions of these configuration words.
Figure 3.2 Expansion General Configuration Tab Screen
3-6
Configuring the Module
3. Click on the Chan. 1 tab (Figure 3.3) and set the I/O Config data
area accordingly. In this example, the 1769-SM2 is configured to
fault if the controller is switched to Program mode, and one drive is
connected at node address 100.
Figure 3.3 Chan. 1 Tab Data Example Screen
Important: When using Multi-Drive mode, the node addresses
entered in the Drive Addr x fields must match the
corresponding drive Parameter 104 - [Comm Node
Addr] value in the PowerFlex 4-Class drives so that the
1769-SM2 module will communicate with the drives.
Note that the DSI Fault Config settings can only be accessed if the
Idle Action is set to “Send Flt Cfg” (Figure 3.4).
Configuring the Module
3-7

4. For each additional channel being used, select its respective tab, set
the desired I/O configuration, and enable the appropriate idle action.
TIP: Alternatively, data can be entered on the Generic Extra Data
Config tab (shown in Figure 3.5 for identification purposes only).
However, with the easy-to-use Chan.1, Chan. 2, and Chan. 3 tabs, there
is no need to enter data on the Generic Extra Data Config tab. But as a
useful reference, this tab does show how the controller stores the data in
the configuration words.
Figure 3.5 Generic Extra Data Config Tab Screen

Configuring the Module
See Table 3.C for descriptions of these configuration words.
5. Click OK when finished. The MicroLogix 1500 will download the
configuration data to the 1769-SM2 module when the controller is
placed in run mode.
Special Case— Data Entry for 2 Stop Bits Communication
The Chan.1, Chan. 2, and Chan 3 tabs do not allow settings that specify 2
stop bits communication in Modbus RTU operation. For this type of
configuration, you must use the Generic Extra Data Config tab to enter
the data by performing these steps:
1. To configure a specific 1769-SM2 module channel for 2 stop bits
communication, click on the Generic Extra Data Config tab.
2. On the Generic Extra Data Config tab screen, enter the appropriate
values from Table 3.D in the offset addresses highlighted in Figure 3.6.

Configuring the Module
Parameter Mode
When the Configuration Mode Switch (SW1 in Figure 2.1) is in the
PARAM (Parameter) position, the 1769-SM2 uses its internal parameter
settings to configure the module. If any configuration data is downloaded
by the controller, it will be ignored.
Important: When the Parameter mode is used, the configuration data
size in the controller should be set to “0.” See Controller
Mode on page 3-3 for more information.
Host PowerFlex 4-Class drives can use this feature since connected DSI
peripheral devices (optional, external PowerFlex 4-Class HIMs,
DriveExplorer with 22-SCM-232, etc.) can access the 1769-SM2 module
directly. However, the 1769-SM2 module must be set to Single mode for
these DSI peripherals to work with the module.

Setting an Idle Action (Single and Multi-Drive Mode)
By default, when the controller is idle, the drive responds by faulting
when using I/O from the 1769-SM2 module. You can respectively
configure a different response to an idle controller using Parameters 04
- [Idle Action 1], 19 - [Idle Action 2], and 34 - [Idle Action 3] for each
channel’s connected drives.
!
ATTENTION: Risk of injury or equipment damage exists.
Parameters 04 - [Idle Action 1], 19 - [Idle Action 2], and 34 - [Idle
Action 3] let you determine the action of each respective channel’s
connected PowerFlex 4-Class drives when the controller is idle. By
default, each parameter faults its respective channel’s drives. You can
set each parameter so that the respective channel’s drives continue to
run. Precautions should be taken to ensure that the settings of these
parameters do not create a hazard of injury or equipment damage.

Configuring the Modbus RTU Master Parameters
In Multi-Drive mode, any module channel can be configured for RTU
Master operation by setting Parameter 07 - [DSI I/O Cfg 1], 22 - [DSI
I/O Cfg 2] or 37 - [DSI I/O Cfg 3] to “5” (RTU Master). When doing
this, additional Modbus RTU Master parameters must be set to complete
that channel’s configuration.
Setting the RTU Baud Rate
By default, each channel set for RTU Master operation uses a 38.4K
baud rate. The values of Parameters 14 - [RTU Baud Rate 1], 29 [RTU Baud Rate 2], and 44 - [RTU Baud Rate 3] set the specific baud
rate used by the respective channel to communicate.
1. Set the values of Parameters 14 - [RTU Baud Rate 1], 29 - [RTU
Baud Rate 2], and 44 - [RTU Baud Rate 3] to the specific baud rate

SEL Important: The RTU Message Timeout value must be considered
when determining the timeout values in the slave nodes.
For example, if five RTU messages are being sent to a
slave node and the slave is powered down, the overall
network cycle time can increase by as much as 10
seconds (5 messages x 2 seconds timeout for each slave
node).
2. Reset the module (see Resetting the Module on page 3-20).
TIP: When configured for RTU Master operation, the RTU Slave
addresses do not get assigned with parameter values. The Slave
address is contained in the message data as described in Chapter 5.

Configuring the Module
Resetting the Module
Changes to switch settings and some module parameters require that you
reset the 1769-SM2 module before the new settings take effect. You can
reset the module by cycling power to the module or by using Parameter
03 - [Reset Module].
!
ATTENTION: Risk of injury or equipment damage exists. If the
module is transmitting control I/O to the drive, the drive may fault when
you reset the module. Determine how your drive will respond before
resetting a connected module.

Channel 3 Enable
“0” = Disables sending output data (Logic Command/
Reference) to the respective channel’s drive(s). All
input (Logic Status/Feedback) data is zeroed (“0”) to
indicate that the data is no longer being updated.
“1” = Enables sending output data (Logic Command/
Reference) to the respective channel’s drive(s). All
respective input data will also be updated.
3…15 Not used
Reserved for future use.
The Module Control Word is a “master” enable/disable switch for
communications on each channel when using the module in Single or
Multi-Drive mode (only DSI operation). The actual output/input data
being sent/received is determined by Parameter 07 - [DSI I/O Cfg 1],
Parameter 22 - [DSI I/O Cfg 2], and Parameter 37 - [DSI I/O Cfg 3].
Important: If the Channel “x” Enable bit is transitioned from ON (1) to
OFF (0), the connected PowerFlex 4-Class drives will fault.
The Channel “x” Enable bits are not used when the module is configured
for Modbus RTU Master operation in Multi-Drive mode.

Understanding the I/O Image
Using Logic Command/Status
The Logic Command is a 16-bit word of control data produced by the
controller and consumed by the 1769-SM2 module. The Logic Status is a
16-bit word of status data produced by the 1769-SM2 module and
consumed by the controller.
This manual contains the bit definitions for compatible products
available at the time of publication in Appendix D. For other products,
refer to their documentation.
Using Reference/Feedback
The Reference (16 bits) is produced by the controller and consumed by
the 1769-SM2 module. The Feedback (16 bits) is produced by the
1769-SM2 module and consumed by the controller.
Valid Reference/Feedback values for PowerFlex 4-Class drives are:
Size
16-bit
(1)
Drive
PowerFlex 4
PowerFlex 4M
PowerFlex 40
PowerFlex 40P
PowerFlex 400
Valid Values (1)
-240.0…240.0 Hz
-400.0…400.0 Hz
-320.00…320.00 Hz
The Reference/Feedback for a PowerFlex 4-Class drive is set in Hz and
not in engineering units like PowerFlex 7-Class drives. For example,
“300” equates to 30.0 Hz (the decimal point is always implied) for all
PowerFlex 4-Class drives—except PowerFlex 400 for which “3000”
equates to 30.00 Hz. In all cases, a minus value equates to reverse
motor direction, and a plus value equates to forward motor direction.

•
Reading/writing drive parameters.
•
Operating as a Modbus RTU Master and initiating Request/Response
messages to Modbus RTU Slave devices, such as PowerFlex 7-Class
drives with 20-COMM-H adapters.
The following table shows various products that can be used with the
1769-SM2 module and whether they support explicit messaging:
Products

Single Mode
The ladder example provided in this section is based on a 1769-SM2
module in slot 1 with one PowerFlex 4/40 drive connected to each
channel (Figure 6.1). The ladder example demonstrates the following
functionality for each channel:
•
•
•
•
Send a Logic Command to control the drive (for example, start, stop).
Send a Reference to the drive and receive Feedback from the drive.
Receive Logic Status information from the drive.
Write and read parameters.
Explicit messaging (parameter read/write) capability varies between the
RSLogix software packages and controllers:
•
Versions of RSLogix 500 before v6.30 do NOT support creating a
Message instruction for the 1769-SM2 module. This limits the
MicroLogix 1500 to performing I/O messaging (Logic Command/
Reference, and Logic Status/Feedback) only.
•
RSLogix 500 v6.30 (or higher) must be used with a MicroLogix
1500 LRP Series C (or newer) controller to create Message
instructions to send explicit messages to the 1769-SM2 module.

Single Mode
The ladder example provided in this section is based on a 1769-SM2
module in slot 1 with one PowerFlex 4/40 drive connected to each
channel (Figure 7.1). The ladder example demonstrates the following
functionality for each channel:
•
•
•
•
Send a Logic Command to control the drive (for example, start, stop).
Send a Reference to the drive and receive Feedback from the drive.
Receive Logic Status information from the drive.
Write and read parameters.
Explicit messaging (parameter read/write) capability varies between the
RSLogix software packages and controllers:
•
Explicit messaging can be used with enhanced CompactLogix
processors, such as the -L31, -L32E, and -L35E.
•
CompactLogix -L20 and -L30 processors do NOT have explicit
messaging capability.

ControlLogix w/1769-ADN DeviceNet
Example Ladder Program
This chapter provides an example of a ControlLogix controller and
1769-ADN Remote DeviceNet adapter system used with a 1769-SM2
module in Single mode.
Important: When the 1769-SM2 module is used with the 1769-ADN,
the Configuration Mode switch (SW1) must be set to the
“Controller” position (default). See Chapter 2 for
information on Configuration Mode switch settings.

The 1769-SM2 module can be operated in Multi-Drive mode when used
in a 1769-ADN system (example not provided). However, explicit
messaging and Modbus RTU Master operation CANNOT be used in
Single or Multi-Drive mode because, at the time of publication, the ADN
does NOT support messaging.
Single Mode
The ladder example provided in this section is based on a 1769-SM2
module in slot 1 with one PowerFlex 4/40 drive connected to each
channel (Figure 8.1). The ladder example demonstrates the following
functionality for each channel:
•
•
•
Send a Logic Command to control the drive (for example, start, stop).
Send a Reference to the drive and receive Feedback from the drive.
Receive Logic Status information from the drive.
ControlLogix w/1769-ADN DeviceNet Example Ladder Program
Explicit messaging (parameter read/write) capability varies between the
RSLogix software packages and controllers:
•
At the time of publication, the 1769-ADN does NOT have explicit
messaging capability. Refer to ADN documentation for possible
future explicit messaging support.

Using RSLinx Classic
To use RSNetWorx for DeviceNet, you must first set up a driver in
RSLinx. RSLinx Classic, in all its variations (Lite, Gateway, OEM, etc.),
is used to provide a communication link between the computer, network,
and controller. RSLinx Classic requires its network-specific driver to be
configured before communications are established with network devices.
To configure the RSLinx driver:
1. Start RSLinx and select Communications > Configure Drivers to
display the Configure Drivers screen.
2. In the Available Drivers pull-down box, select “DeviceNet Drivers
(1784-PCD/PCIDS, …drivers” and then click Add New… to display
the DeviceNet Driver Selection screen.
3. Select the PC communication card (1770-KFD, 1771-SDNPT, etc.)
for connection of your computer to the network and then click
Select.
4. Configure the driver for your computer and network settings and
click OK.
ControlLogix w/1769-ADN DeviceNet Example Ladder Program
8-3
5. In the Add New RSLinx Driver screen, use the default name or type a
new name and click OK. The Configure Drivers screen reappears
with the new driver in the Configured Drivers list (Figure 8.2).
Figure 8.2 Configure Drivers Dialog Box with a Configured Driver
6. Click Close to close the Configure Drivers screen. Keep RSLinx
running.
7. Verify that your computer recognizes the drive. Select
Communications > RSWho and, in the treeview, click the “+”
symbol next to the DeviceNet driver.
Using RSNetWorx for DeviceNet
RSNetWorx for DeviceNet is a Rockwell Software application that can
be used to set up DeviceNet networks and configure connected devices.
You can view the devices on a DeviceNet network by going online. A
device may appear as an unrecognized device (node 63 in Figure 8.3) if
RSNetWorx for DeviceNet does not have an EDS file for it.
Step
1. After setting up a driver in RSLinx (see Using RSLinx Classic on
page 8-2), start RSNetWorx for DeviceNet.
2.
3.
Select Network > Online. If the Browse for Network dialog box
appears, RSLinx has multiple drivers configured. Select your
DeviceNet network, and click OK. A prompt appears.
Click OK to go online. The devices on the network appear in the
Configuration View. You can select Graph, Spreadsheet, or Master/
Slave views. Figure 8.3 shows an example network in a Graph view.

Troubleshooting
Viewing and Clearing Events
The module has an event queue to record significant events that occur in
the operation of the module. When such an event occurs, an entry is put
into the event queue. You can view the event queue using DriveExplorer
v3.01 (or higher) software.
Figure 9.2 DriveExplorer Event View/Clear Screen
The event queue can contain up to 32 entries. Eventually the event queue
will become full, since its contents are retained through module resets.
At that point, a new entry replaces the oldest entry. Only an event queue
clear operation or module power cycle will clear the event queue
contents.
Resetting the module to defaults has no effect on the event queue.
Many events in the event queue occur under normal operation. If you
encounter unexpected communications problems, the events may help
you or Allen-Bradley personnel troubleshoot the problem. The following
events may appear in the event queue:

A “0 = Not Stop” condition (logic 0) must first be present before a “1 = Start” condition will start the drive. The Start command acts as
a momentary Start command. A “1” will start the drive, but returning to “0” will not stop the drive.
Depending on the PowerFlex 4-Class drive, the functions for bits 6, 7, and 15 change. Refer to Appendix C in the PowerFlex 4,
PowerFlex 4M, PowerFlex 40 or PowerFlex 40P drive User Manual, or Appendix E for the PowerFlex 400 drive bit functions.
The functions for these bits are the same for all PowerFlex 4-Class drives—including the PowerFlex 40P when it is used in the
“Velocity” mode. When using the PowerFlex 40P in the “Position” mode, the bit functions are different. For details, refer to Appendix C
in the PowerFlex 40P User Manual.

Glossary
C
CIP (Common Industrial Protocol)
CIP is the transport and application layer protocol used for messaging
over EtherNet/IP, ControlNet, and DeviceNet networks. The protocol is
used for implicit messaging (real time I/O) and explicit messaging
(configuration, data collection, and diagnostics).
Class
A class is defined by the DeviceNet specification as “a set of objects that
all represent the same kind of system component. A class is a
generalization of an object. All objects in a class are identical in form
and behavior, but may contain different attribute values.”
ControlFLASH
An Allen-Bradley software tool that lets users electronically update
firmware on printed circuit boards.
Controller
A controller, also called programmable logic controller, is a solid-state
control system that has a user-programmable memory for storage of
instructions to implement specific functions such as I/O control, logic,
timing, counting, report generation, communication, arithmetic, and data
file manipulation. A controller consists of a central processor, input/
output interface, and memory. See also Scanner.
D
DeviceNet Network
An open producer/consumer Controller Area Network (CAN) which
connects devices (for example, controllers, drives, and motor starters).
Both I/O and explicit messages can be transmitted over the network. A
DeviceNet network can support a maximum of 64 devices. Each device
is assigned a unique node address and transmits data on the network at
the same data rate.
A cable is used to connect devices on the network. It contains both the
signal and power wires. Devices can be connected to the network with
drop lines, in a daisy chain connection, or a combination of the two.
General information about DeviceNet and the DeviceNet specification
are maintained by the Open DeviceNet Vendor’s Association (ODVA).
ODVA is online at http://www.odva.org.
DSI (Drive Serial Interface)
DSI is based on the Modbus RTU serial communication protocol and is
used by various Allen-Bradley drives, such as PowerFlex 4-Class drives.
Glossary-2
DSI Peripheral
A device that provides an interface between DSI and a network or user.
Peripheral devices are also referred to as “adapters” or “modules.” The
1769-SM2 module, 1203-USB or 22-SMC-232 converter, and
PowerFlex 4-Class HIMs (22-HIM-A3 or 22-HIM-C2S) are examples of
DSI peripherals.
DSI Product
A device that uses the DSI communications interface to communicate
with one or more peripheral devices. For example, a motor drive such as
a PowerFlex 4-Class drive is a DSI product. In this manual, a DSI
product is also referred to as “drive” or “host.”
DriveExplorer Software
A tool for monitoring and configuring Allen-Bradley products and
modules. It can be run on computers running various Microsoft
Windows operating systems. DriveExplorer version 2.xx (or higher) can
be used to configure this module and connected PowerFlex drives.
Information about DriveExplorer software and a free lite version can be
accessed at http://www.ab.com/drives/driveexplorer.
DriveTools SP Software
A software suite designed for running on various Microsoft Windows
operating systems. This software suite provides a family of tools,
including DriveExecutive, that you can use to program, monitor, control,
troubleshoot, and maintain Allen Bradley products. DriveTools SP can
be used with Allen-Bradley drives. Information about DriveTools SP can

EDS (Electronic Data Sheet) Files
Simple text files that are used by network configuration tools such as
RSNetWorx for DeviceNet to describe products so that you can easily
commission them on a network. EDS files describe a product device type
and revision. EDS files for many Allen-Bradley products can be found at
http://www.ab.com/networks/eds.
Explicit Messaging
Explicit Messages are used to transfer data that does not require
continuous updates. They are typically used to configure, monitor, and
diagnose devices over the network.
F
Flash Update
The process of updating firmware in a device. The module can be flash
updated using various Allen-Bradley software tools. Refer to Flash
Updating the Module on page 3-22 for more information.
Glossary-3
H
HIM (Human Interface Module)
A device that can be used to configure and control a drive. PowerFlex
4-Class HIMs (22-HIM-A3 or 22-HIM-C2S) can be used to configure
PowerFlex 4-Class drives and their connected peripherals.
Hold Last
When communication is disrupted (for example, the controller is idle),
the module and PowerFlex drive can respond by holding last. Hold last
results in the drive receiving the last data received via the network
connection before the disruption. If the drive was running and using the
Reference from the module, it will continue to run at the same
Reference.
I
Idle Action
An idle action determines how the module and connected drive act when
the controller is switched out of run mode.
I/O Data
I/O data, sometimes called “implicit messages” or “input/output,” is
time-critical data such as a Logic Command and Reference. The terms
“input” and “output” are defined from the controller’s point of view.
Output is produced by the controller and consumed by the module. Input
is produced by the module and consumed by the controller.
L
Logic Command/Logic Status
The Logic Command is used to control the PowerFlex 4-Class drive (for
example, start, stop, direction). It consists of one 16-bit word of output to
the module from the network. The definitions of the bits in this word
depend on the drive, and are shown in Appendix D.
The Logic Status is used to monitor the PowerFlex 4-Class drive (for
example, operating state, motor direction). It consists of one 16-bit word
of input from the module to the network. The definitions of the bits in
this word depend on the drive, and are shown in Appendix D.
N
NVS (Non-Volatile Storage)
NVS is the permanent memory of a device. Devices such as the module
and drive store parameters and other information in NVS so that they are
not lost when the device loses power. NVS is sometimes called
“EEPROM.”
O
Objects
The CIP common specification defines an object as “an abstract
representation of a particular component within a product.”
Glossary-4
P
PCCC (Programmable Controller Communications Command)
PCCC is the protocol used by some controllers to communicate with
devices on a network. Some software products (for example,
DriveExplorer and DriveExecutive) also use PCCC to communicate.
PowerFlex 4-Class (Component Class) Drives
The Allen-Bradley PowerFlex 4-Class family of drives supports DSI and
includes the PowerFlex 4, PowerFlex 4M, PowerFlex 40, PowerFlex
40P, and PowerFlex 400. These drives can be used for applications
ranging from 0.2…110 kW (0.25…150 HP).
R
Reference/Feedback
The Reference is used to send a setpoint (for example, speed, frequency,
torque) to the drive. It consists of one 16-bit word of output to the
module from the network.
Feedback is used to monitor the speed of the drive. It consists of one
16-bit word of input from the module to the network.
RSLogix 500/5000
RSLogix software is a tool for configuring and monitoring controllers to
communicate with connected devices. It is a 32-bit application that runs
on various Windows operating systems. Information about RSLogix
software can be found at http://www.software.rockwell.com/rslogix.
RSNetWorx for DeviceNet
A software tool for configuring and monitoring DeviceNet networks and
connected devices. It is a 32-bit application that runs on various
Windows operating systems. Information about RSNetWorx for
DeviceNet software can be found at http://www.software.rockwell.com/
rsnetworx.
RTU Baud Rate
The baud rate is the speed at which data is transferred when the
1769-SM2 module is operating in Multi-Drive mode and the DSI I/O
Cfg parameter for a channel is set to “5” (RTU Master). The available
baud rates are:
38.4K bps
19200 bps
9600 bps
4800 bps
2400 bps
1200 bps
600 bps
300 bps
Glossary-5
S
Scanner
A scanner is a separate module (of a multi-module controller) or a
built-in component (of a single-module controller) that provides
communication with modules connected to a network. See also
Controller.
Status Indicators
Status indicators are LEDs that are used to report the status of the
module, network, and drive. They are on the front of the module.
Z
Zero Data
When communication is disrupted (for example, the controller is idle),
the module and drive can respond with zero data. Zero data results in the
drive receiving zero as values for Logic Command and Reference data. If
the drive was running and using the Reference from the module, it will
stay running but at zero Reference.
